The Proof Research Carbon Fiber Barrel in 6.5 PRC (brand part number 123225) is a direct-fit replacement barrel built for Defiance-pattern actions, measuring 24 inches in a Sendero contour and threaded 5/8-24 at the muzzle for a brake or suppressor. Like the rest of Proof’s carbon-fiber lineup, it wraps a reduced-profile stainless steel core in aerospace-grade carbon fiber, cutting weight substantially compared to an equivalent all-steel barrel while holding match-grade accuracy. The barrel is cut with a 1:7.5 twist to stabilize heavier 6.5 PRC bullets, and the finished assembly weighs 3 pounds, a meaningful savings for a long-range hunting or precision build carried in the field.
